Recently I bought ten Sony CR2032 “calculator” watch batteries from Amazon. At least, I thought that I did. Here’s the description: Sony Lithium 3V Batteries CR2032 10 pack by Sony. The actual seller is an unknown entity called Wholesale Batteries.
The first four batteries that I used ran out of steam within a few hours. I measured the open circuit voltage for two unused batteries from the ten. They measured about 3.04 Volts.
Either these batteries have been stored at elevated temperatures or they are counterfeits.
I’ve learned that counterfeiting of calculator batteries is indeed a problem:
If counterfeiting remains a problem on Amazon, it risks falling into the dubious eBay seller category. Somehow, Amazon needs to impose quality control on its independent sellers.
